1m;- H-L Masons-e, a subject of the Grown of l Britain, both residing at Salt Lake City,v in the county of Salt Lake and State of'IJtah, have invented. certain. new and use tel Improvements in Goncrete Frames for Door and Window Openings, of which the follbwing isa specification.

Our invention relates toframe members: for doors, windows, arches, etc, made as jambs, lintels' and. sills, which are cast or formed of some mineral composition torender them fire proofand it consistsina novel construction and arrangement of the parts of such: members made of reinforced concrete and formed entire as a new article of manufacture ready to be set up in the wall to make a ht, substantial and: fire proof filling aroun such openings, as will be hereinafter more fully described with reference to the drawing, in which- Figure 1, is a face view of adoor frame, Fig. 2, a similar view of a window frame, Fig. 3, is a cross-sectional view on a larger scaleof the door jamb member, showing our novel construction, Fig. 4:, is a similar crosssection on a still. larger scale, showing. the window jambmember, Fig. 5, is a crosssection through. the window sill, on line- 5-5 of Fig. 2, and Fig. 6-, is a cross-section through the lintel' on l'ine= 6-6 of Fig. 1.

In the drawing Fig. 1, A A represent the jambmembers of the door. These may be molded, as at Al, or plain as at A B represents the lintel which may alsobe made Wlth an ornamental face as shown in Fig. 1:, or be plain as shown at B in Fig. 2. G C represent the jambi members of the win- (low and? these in like manner may be plain or ornamental, a" molded form ofuniform cross section. being shown at C and a figured form at C The construction of these members is best shown in detail in Figs. 3' to 6.

Referring to Fig. 3, which is the jamb member for a door, the body 1 of the same is formed of concrete having a large longitudinal channel 4 on its back side where it joins on tothe-wall, shown dotted lines at m. This channel is narrower at its outlet on v the face than it is inside for the purpose of allowin the concrete-w, or other material of which tie wall is formed, to be keyed into the jamb member, so that the latter cannot pull away from the wall. Inthe outer face of the jamb member the concrete is molded to form a shallow channel with flaring edges in which is permanently seated a jamb' facing. 5- of wood or other material. Between this woodfacing and the concrete is. a thin layer 7 of some water proof material, such as tar a-per or the like, which: preventsthewood from absorbing the water from thewet concrete and warping. Instead of this layer of water proof material, the contacting face of the wooden jamb may be painted or coated with asphaltum, or other water 4 resisting paint The wooden jamb facing is made a permanently attached part of the concrete body and for this purpose headed nails 6 are driven into the wooden j'amband the concrete is molded around the heads so as to bond the casin concrete. Centrally within the b0 y of the concrete is embedded a reinforcing of woven wire 2 which extends longitudinally fromendto end of the jam-b member and which in transverse section is U-shaped andeX- tend's well out into the flanges of the concrete on each side of the channel's. Com meeting with this reinforcing and extending out through the concrete into the back chanml 1 are bond wires 3' which, when embedded into the concrete of the wall a, make a firm union. There are a number ofv these wires which extends from the concrete on the side next to the channel into the latter and terminate in free terminal ends. These ends are capable of being deflected back and forth and embedded by suitable bends or intertwists in the concrete wall filling w as it is packed in the channel, to make a very firm bond. As a further reinforcement, metal rods 7 are embedded longitudinally in the concrete. In Fig. 3, the sides of the body of the concrete member are/extended beyond the vertical plane of the wall m andform the molded architraves of the door without other casings.

In Fig. 4, the same general construction is employed for thejamle members of the t0 this:

.the reinforcing 0 windows; thus 1' is the concrete body, 2'

wire extendmg into the flanges 3 the nd wires, 4 the back channel and 8 the jamb facings for the sash to slide in. In this instance a second channel 9 is formed for the weights of the sash to play in, as seen in dotted lines and on one side of this weight channel, a side strip of crete, 2 the reinforcenient of wire, 4 chan-.

nels on the lower side, 5 a Wooden facing to form the stool, 6 the headed nails connecting the same to the concrete and 7 d the water roof lining.

In Big. 6, showing the l ntel, 1 1s the concrete body, 2 the reinforcmg Wire, 3 the bond wires, 4' the back channel, 5 the wooden facing, 6" the headed nails, and 7 the water proof lining.

The j ambs, liutels and sills are to be made complete in various lengths and sizes ready to be put up, but the jambs may be made 1n sections for large doors and windows if desired.

- Some of the advantages we claim for these frame members are that they'are fire roof and can beused on any kind of buildmg. That they make possible a perfect bond between jambs and wall, thereby positively excluding draft or flame. They become by.

their peculiar shape and reinforcement one with the walls, thereby strengthenin and bracing the walls, especially brick wa ls, to a" very great extent. They are constructed especially to be used in connection with a system of wall construction where the ambs are set up and the wall mold worked from one to the other. They are more economical than any other frames, as when they are set up the opening is cased 0n the inside as well as outside, reducing the carpenters work to a minimum. By using these jambs full casings are always obtained in the corners of rooms, as the jamb with casings on is always set before the walls are built, or where the casings are omitted it is deep enough to prevent the wall coming too close for the casings. l/Vhere lumber casings are wanted,

wood blocks are cast in the jambs for the perfect fastening of these. By using these jambs, the putting on of plastering grounds becomes unnecessary as the j ambs are alwavs straight and afford a better gage for the plastering than anything else that'could be used, as it always gives the thickness of the wall and thereby prevents all trouble with putting up finishing trimmings.

doors, windows, etc., consisting Although these frame members are designed to be made and sold as separate articles of manufacture, we may form them around the openings at the same-time that the adjoining walls are built.
